Filed: 1975-06-10
Abstract: 1505753 Zig-zag sewing machine HUSQVARNA AB 10 June 1975 [13 June 1974] 24727/75 Heading D1G In a zig-zag sewing machine the needle bar jogging and/or work feed mechanisms are actuated by a device which comprises two cam discs comprising axial cams having their cam faces directed towards each other and rotatable about their common axis to displace themselves relatively to each other. Sets of such cams 42, 43 are mounted on a splined shaft 45 oscillated by mechanism 56. Cam 42 has keys 46 engaging the shaft splines and oscillates with shaft 45. Cam 43 has peripheral teeth 48 48' 48" at a spacing such that during anticlockwise movement of cam 43 with cam 42 tooth 48' does not reach pallet 32 of a pawl 29 which is positioned in the full line position when electromagnetic coil 35 is energised. The cams then oscillate together. When coil 35 is de energised pallet 33 will engage behind tooth 48" and the cams rotate relatively their cam faces moving them axially apart. In Fig. 6 the cams on the right are shown in their position with the coils energised, those on the left are in the position resulting from the de-energisation of the coil. Each cam stack increases in length by the sum of the separations of the cam sets constituting the stacks: the individual movement of the successive sets in each stack 24, 25 is made to accord with the expression 2<SP>n</SP> to provide movements in the ratio of 1, 2, 4, and 8. Thus, selective operation of the coils 35 of each set provides a stack elongation of a selected amount of between 0 and 15 units. The elongation moves rods 13, 51 respectively engaged by transverse pins 49, 50 with the respective stacks 25, 24. Rods 13, 51 are respectively connected to the needle bar gate and the feed mechanism. In a modification (Fig. 4 not shown) balls (60) are provided in one cam plate and a wave shaped path (61) is provided on the other. In a further modification (Fig. 9 not shown) the cam sets are rocked by levers (64) extending therefrom to a common, external, actuating rod (63), which replaces the action of the splined shaft 45.

Title: Improved method of and mechanism for transferring fabric to needles of a knitting machine
IPC: H01R13/58
Filed: 1935-09-05
Abstract: 451,159. Knitting- machines. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.- (Assignees of Lawson, R. H. ; 55, Cooke Street, Pawtucket, Gagne, A. ; 107, Hendrick Street, Central Falls, and Cloutier, A. N. ; 497, Broad Street, Lonsdale, all in Rhode Island, U.S.A.) Sept, 5, 1935, No. 24790. Convention date, Sept. 13, 1934. [Class 74 (ii)] In a circular knitting-machine having a movable sinker assembly which is raised when fabric is transferred from a transfer ring to the needles of the machine, safety means operated by controlling- mechanism is provided to prevent displacement of the sinker assembly except when the machine is in proper position for transfer. Just prior to transfer of, say, a rib top to the machine, the needles are levelled, the sinkers 21, Fig. 4, are raised so that their throats are about level with the tops of the needle hooks, and thus the points 25 of the transfer ring, entering between the sinkers, are guided thereby to the needles. The sinker head 16 is carried by the inner portion 12 of a bipartite needle cylinder, which portion can be raised by means of a foot pedal 41, Fig. 1, an abutment plate 51, controlled by a cam 42 carried on an extension of the main cam shaft 44, preventing movement of the pedal except at the proper times. In a modification, Fig. 6, (not shown), a latch 64, similarly cam-operated, takes the place of the plate 51. The transfer ring may comprise an inner member 24, and an outer clamping member 26, holding in position, the points 25. In a modification, Fig. 10, a gripping handle 74 may be provided, integral with a clamping member 75 having a bevelled lower edge, the clamping member engaging centring lugs 78 attached to the sinker cap 22. In a further modification, Fig. 11, the transfer point assembly can rotate freely within a ring 79 carrying centring lugs 82, by reason of steel balls running in a groove formed in the outer periphery of clamping member 26<1>, and thus, when the shoulders 83 of the lugs 82 have been rested on the sinker cap 22, the points may be rotated, to align them with the gaps between the sinkers. In a still further modification, Fig. 14, strippers 96 may be made to strip the fabric from the points 25, on to the co-operating needles, by depressing an inner sleeve 87, with respect to the transfer points 25, against the action of springs 93, axial rotation being prevented by a pin 90 riding in a groove 89 formed in a body member 84. The strippers are held in position by a spring band 101 engaging recesses in the strippers.

Title: Process for treating carbonaceous materials to obtain distillation products such as hydrocarbons, metallised coke and the like
IPC: C10B57/06
Filed: 1928-08-29
Abstract: 296,443. Fabrique Nationale de Produits Chimiques et d'Explosifs Soc. Anon. Sept. 2, 1927, [Convention date]. Materials for making coke.-In the carbonization of coal, lignite, peat, or oil shale, oxidizing agents such as iron or manganese oxides or alkaline or alkaline earth carbonates are added to the charge before treatment. A larger yield of tar takes place, which is lighter and similar to crude petroleum. The resulting coke is hard, coherent, and very porous and is suitable for use in blast furnaces. If the additions consist of pulverulent iron ore , residues of roasted .pyrites, or manganese ore, these ores become agglomerated in the coke and may be charged with the latter into the reducing apparatus. The Specification as open to inspection under Sect. 91 (3) (a) states also that the coke containing metallic oxides or finely divided metals, may be used as a catalyst to produce by direct synthesis, condensable hydrocarbons and alcohols from the carbonic oxide, hydrogen, and gaseous hydrocarbons produced by the distillation. This subject-matter does not appear in the Specification as accepted.
